The
backup listhosts command displays the Backup Database record of the
port offset numbers defined for Tape Coordinator machines. A Tape Coordinator
must have an entry in the list to be available for backup operations.
The existence of an entry does not necessarily indicate that the Tape
Coordinator process (
butc) is currently running at that port offset.
To check, issue the
backup status command.
- -localauth
- Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The backup command
interpreter presents it to the Backup Server, Volume Server and VL Server
during mutual authentication. Do not combine this flag with the
-cell argument. For more details, see backup(8).
-
-cell <cell name>
- Names the cell in which to run the command. Do not combine
this argument with the -localauth flag. For more details, see
backup(8).
- -help
- Prints the online help for this command. All other valid
options are ignored.
After a "Tape hosts:" header, the output reports two things about each
Tape Coordinator currently defined in the Backup Database:
- •
- The hostname of the machine housing the Tape Coordinator.
The format of this name depends on the hostname format used when the
backup addhost command was issued.
- •
- The Tape Coordinator's port offset number.
The Tape Coordinators appear in the order in which they were added to the Backup
Database.
The following example shows the result of the command in the Example Corporation
cell:
% backup listhosts
Tape hosts:
Host backup1.example.com, port offset 0
Host backup1.example.com, port offset 1
Host backup3.example.com, port offset 4
Host backup2.example.com, port offset 3
The issuer must be listed in the
/etc/openafs/server/UserList file on
every machine where the Backup Server is running, or must be logged onto a
server machine as the local superuser "root" if the
-localauth flag is included.
